Technical Field

[0001] The utility model relates to the technical field of water ecological restoration, in particular to a water ecological restoration simulation device for a heavily polluted river. Background Art

[0002] Water ecology refers to the impact of environmental water factors on organisms and the adaptation of organisms to various water conditions. Life originated in water, and water is an important component of all organisms. Organisms continuously exchange water with the environment. The quality (salinity) and quantity of water in the environment are important factors that determine the distribution of organisms, species composition and quantity, and lifestyle.

[0003] At present, the living standards in cities continue to improve, and the daily wastewater and sewage are usually discharged into the rivers and canals in the city, which causes serious pollution to the river water ecology. Since the river water ecological restoration work is relatively large, the staff needs to constantly decide which restoration device is suitable through trial and error. However, the existing water ecological restoration simulation devices are relatively simple and are not conducive to the use of heavily polluted rivers.

[0004] To this end, we designed a simulation device for ecological restoration of heavily polluted river water. Utility Model Content

[0005] The utility model aims to solve the problem that the prior art is not conducive to the use of heavily polluted rivers and proposes a water ecological restoration simulation device for heavily polluted rivers.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model sets up the infiltration chamber and the water diversion pipe, so that the polluted water in the river can be filtered by the filter plate before entering the simulation box, and the filtering effect of the water can be concentrated. At the same time, the infiltration chamber can improve the efficiency of water filtration and reduce the content of pollutants in the water. At the same time, the water diversion pipe can avoid effective decentralized filtration in the case of water congestion, so that part of the unfiltered water can enter the first planting chamber for centralized purification and filtration again, which can effectively improve the simulated purification effect of the polluted water.

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A heavily polluted river water ecological restoration simulation device includes a simulation box 1, which is composed of multiple plastic plates and metal plates. At the same time, the water inlet chamber 2 opened at the left end of the simulation box 1 is mainly opened by the staff to put in polluted water. At the same time, the side wall of the simulation box 1 is set by a transparent plate, which is convenient for the staff to understand the current water purification progress. The first planting chamber 3 is opened at the right end of the simulation box 1, the upper part of which is used to plant phytoplankton, and the lower part is used to purify unfiltered water, and the roots of phytoplankton assist in filtering the water. The hook is fixed to the bottom of the simulation box 1, and its function can realize the function of fixing the simulation box 1 on the bottom and the surface of the water. By binding heavy blocks to the hook, the bottom sinking restoration work of the simulation box 1 can be realized. By combining floating objects and some weight blocks, the simulation box 1 can float on the water surface or the middle layer of the water body for restoration.

[0022] A filter plate 4 for filtering water is provided in the water inlet chamber 2. The filter plate 4 is composed of a variety of filter materials and has honeycomb characteristics inside, which can effectively collect impurities and particles in the water. The filter plate 4 is fixedly connected to the inner wall of the water inlet chamber 2 by fasteners. An infiltration chamber 7 for guiding the filtered water is provided in the water inlet chamber 2. The infiltration chamber 7 facilitates the water to pass through the filter plate 4 and flow into the simulation box 1. The infiltration chamber 7 is connected to the first planting chamber 3, and most of the water in the infiltration chamber 7 flows into the first planting chamber 3.

[0023] The water inlet chamber 2 is provided with a plurality of water diversion pipes 6 for guiding the water body. The water diversion pipes 6 are used to prevent the water body in the water inlet chamber 2 from being difficult to penetrate and to divert the water body. The water diversion pipes 6 are linearly arranged on the side wall of the water inlet chamber 2. The number of arranged water diversion pipes 6 depends on the specifications of the inner wall of the simulation box 1, and one end is connected to the first planting chamber 3, and all are discharged into the first planting chamber 3. The water diversion pipes 6 are provided with a plurality of water diversion holes 8 for increasing the water diversion amount. The water diversion holes 8 are conducive to the rapid entry of water into the first planting chamber 3.

[0024] The first planting cavity 3 is provided with a plurality of phytoplankton fixing cavities 5 for planting phytoplankton. The phytoplankton fixing cavities 5 are connected with the first planting cavity 3 to facilitate the extension of the roots of the phytoplankton to the bottom of the first planting cavity 3, thereby assisting in water purification and repair.

[0025] The first planting cavity 3 is provided with a particle adsorption plate 9 for collecting particulate matter. The particle adsorption plate 9 is composed of existing activated carbon. The activated carbon is concentrated and compacted and laid in the groove through mesh filling. The first planting cavity 3 is symmetrically fixed with a fixing part 10. The fixing part 10 is used to hang the particle adsorption plate 9 to separate the interior of the simulation box 1 from the first planting cavity 3. The fixing part 10 is provided with a groove for fixing the particle adsorption plate 9, and the particle adsorption plate 9 is adapted to the groove through an auxiliary block. The auxiliary block is a fixed clamping component. The fixing part 10 is provided with a fine screen 11 for guiding water to enter the simulation box 1. The fine screen 11 is provided with a plurality of holes with smaller apertures, which are staggered and can effectively block particles and pollutants in unfiltered water and allow water to enter the simulation box 1.

[0026] A plurality of underwater plant fixing cavities 12 for planting underwater plants are provided in the simulation box 1, which are mainly used for planting underwater plants and completing the water body repair work inside the simulation box 1. A second planting cavity is provided in the simulation box 1 and is connected with the fine screen 11. The underwater plant fixing cavities 12 are linearly arranged in the second planting cavity. The underwater plant fixing cavities 12 are opened according to the bottom plate specifications of the simulation box 1. A plurality of anti-blocking holes 14 for reducing particle congestion are provided on the infiltration cavity 7. The anti-blocking holes 14 are mainly used to prevent a certain part of the infiltration cavity 7 from being blocked and temporarily unable to be cleaned. In order to allow the water purification to continue to work, the filtered water body is infiltrated through the anti-blocking holes 14 into the simulation box 1, which can relieve the water pressure. A plurality of swinging pieces 13 for improving the swing of underwater plants are provided on the side wall of the simulation box 1. The swinging pieces 13 are symmetrically arranged on the inner and outer walls of the simulation box 1 and are connected by auxiliary shafts. The outer wall swinging pieces 13 follow the flow of the water layer and are transmitted to the inside of the simulation box 1, and improve the swinging effect of the internal underwater plants, which can effectively improve the water purification efficiency inside the simulation box 1.

[0027] The working principle of the utility model is as follows: the staff puts the polluted water into the water inlet chamber 2 in the simulation box 1 through a container, and the water enters the infiltration chamber 7 and the water pipe 6 under the penetration of the filter plate 4, and then the water is concentrated at the bottom of the first planting chamber 3, and the preliminary pollutant screening of the water is completed under the work of the particle adsorption plate 9 and the fine screen 11. At the same time, the roots of phytoplankton will also assist in the purification and repair work. Finally, the water enters the simulation box 1 and is concentratedly purified by many underwater plants.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
